Hershi D.
Start a project

I build the websites and systems businesses actually run on.

I am Hershi, a freelance developer in London. Below are nine sites I built for real businesses. Every one is live right now, and you can go and use them. I work in English, Hebrew and Yiddish.

Keep scrolling. The page takes on each client's colour as you go.

The velvlkirshenbaum.com site

דער ירושלימער

A Yiddish video and podcast platform: series, episodes, a status feed and a paid tier.

Built the whole thing and still run it.

The interface reads right to left because it was laid out that way, not because a stylesheet flipped it at the end. Yiddish needs the digraphs to render as single letters, which rules out most webfonts before you start.

  • Language Yiddish, right to left
  • Scope Site, player, memberships
The kehillavoice.com site
kehillavoice.com

Voice broadcasting: record once, deliver it to thousands of phones, watch the delivery come back live.

Built the platform and the sending dashboard.

The hard part is not sending calls, it is telling somebody honestly how many landed. The dashboard reports per-broadcast delivery as it happens rather than a total at the end.

  • Built for Community broadcasting
  • Shows Live delivery per broadcast
The ermanna-fashion.com site
ermanna-fashion.com

An Italian fashion house: collections, an archive, and the stores that carry them.

Built it, and I still maintain it.

The whole first screen is a video with the wordmark over it, which is easy to make look cheap. It holds up because the type sits on the one part of the frame that stays dark as the footage moves.

  • Sector Luxury fashion
  • Shown Collection, archive, stockists
The assistlynk.com site
assistlynk.com

One console for a client-service team: contacts, scripts, credentials and every channel in a single place.

Built the product.

Built for operators, so it is dense on purpose. The whole design brief was that somebody on their fourth hour of calls should never have to hunt for a credential.

  • Built for Client-service operators
  • Access Private, behind a login

Nine sites, one person.

There is no studio behind this. The person who quotes your job is the person who writes the code, and the person who picks up the phone two years later when something needs changing.

I write everything from scratch. No page builders, no themes to license, nothing you have to keep paying a third party for. That is slower to start and much cheaper to live with.

Most of what I know came from running my own products and having to keep them alive at three in the morning. It is a different education from building something once and walking away.

Group travel and events: trips, private charters, and the booking that sits behind them.

Built the site and the booking flow.

Travel copy wants to shout. This one is set in a serif on a deep teal and says almost nothing on the first screen, which is why the booking form gets read.

  • Handles Trips, events, charters
  • Includes Booking and management
The mosdos.tech site
mosdos.tech

Mosdos Technology Office

Device compliance for Jewish institutions: register a device, verify its filter, issue the certificate.

Built the system end to end.

It issues real certificates that a school has to trust, so the interesting work is all in the audit trail and in making sure a record cannot quietly change after it is signed.

  • Handles Registration, verification, certificates
  • Users Institutions and their families
The tools4teens.org.uk site
tools4teens.org.uk

A UK charity giving disadvantaged 16 to 19 year olds a trade and a way into work.

Built the site.

A charity site fails when it looks either slick or sad. This one leads with photographs of the actual workshops, because the proof that the programme is real is that you can see it happening.

  • Ages 16 to 19
  • Registered United Kingdom
The aycf.app site
aycf.app

Live seat availability for Wizz Air All You Can Fly, polled from the airline rather than guessed.

Built it and I run the polling.

The whole product is a race against rate limits. It polls per flight rather than per route, and the two accounts it uses go out through different addresses so neither hits the ceiling.

  • Covers 160+ origins
  • Data Polled live, not scraped from PDFs
The grab.hershi-d.com site
grab.hershi-d.com

Paste a link from almost anywhere, get the file back. No account, no install.

Mine. I built it and I pay for it.

This one is on the list because it is the honest example: it is my own, it gets real traffic, and it is where I test the boring infrastructure before I put it near a client.

  • Mine, not a client's Free to use
  • Also Works inside Telegram

What you can hold me to.

When I answer

Usually within a few hours, in English, Hebrew or Yiddish. If I am deep in something I will still tell you when I can start.

Who owns it

You do, from day one. The code, the domain and the server are in your name, and you can hand them to any other developer without asking me.

Handover

Every project ships with written notes on how it works and how to run it. If I disappear tomorrow, the next person can pick it up.

When it breaks

I fix it. Not a support plan you pay monthly for, just the thing you should expect from whoever built it.

Tell me what you need built.

In your own words, however rough. If it is not something I should be doing, I will say so and point you at someone better placed.

I read every message myself.
